mainboard/google/kahlee: Reset trackpad & touchscreen
AMD chips don't hold off a reset to the end of I2C transitions, so
devices on the i2c bus can be left in a bad state. To avoid this,
make sure the trackpad and touchscreen chips get disabled
during boot.
BUG=b:114411165
TEST=build, reboot watch trackpad enable go low
